* [PPC440SPe] Improve PCIe configuration space accessGrzegorz Bernacki2007-09-07-31/+97
| | | | | | | | | | | | | - correct configuration space mapping - correct bus numbering - better access to config space Prior to this patch, the 440SPe host/PCIe bridge was able to configure only the first device on the first bus. We now allow to configure up to 16 buses; also, scanning for devices behind the PCIe-PCIe bridge is supported, so peripheral devices farther in hierarchy can be identified.

* [PPC440SPe] Convert machine check exceptions handlingGrzegorz Bernacki2007-09-07-44/+37
| | | | | | | | | | | | | | | | Convert using fixup mechanism to suppressing MCK for the duration of config read/write transaction: while fixups work fine with the case of a precise exception, we identified a major drawback with this approach when there's an imprecise case. In this scenario there is the following race condition: the fixup is (by design) set to catch the instruction following the one actually causing the exception; if an interrupt (e.g. decrementer) happens between those two instructions, the ISR code is executed before the fixup handler the machine check is no longer protected by the fixup handler as it appears as within the ISR code. In consequence the fixup approach is being phased out and replaced with explicit suppressing of MCK during a PCIe config read/write cycle. Signed-off-by: Grzegorz Bernacki <gjb@semihalf.com>
* lib_ppc: make board_add_ram_info weakKim Phillips2007-08-18-2/+0
| | | | | | | | | | | | platforms wishing to display RAM diagnostics in addition to size, can do so, on one line, in their own board_add_ram_info() implementation. this consequently eliminates CONFIG_ADD_RAM_INFO. Thanks to Stefan for the hint. Signed-off-by: Kim Phillips <kim.phillips@freescale.com>
